Based on the search results, a 72-inch (6-foot) round table can seat up to 8 adults. This means that a 72-inch round table would be suitable for seating 8-10 people comfortably. However, it is important to note that the number of people that can fit at a table depends on various factors such as the size of the chairs, the type of event, and the amount of space needed for formal table settings. If the guests will be seated for long periods of time, it is recommended to go with the smaller number of people to provide extra space for formal table settings and to ensure that guests have enough elbow room. Additionally, if bulky chairs or chairs with arms are used, it is recommended to go with the smaller number of people to ensure that the chairs fit comfortably.
